Sustainable and scalable one-pot synthesis of diaryliodonium salts.

Two one-pot routes from iodoarenes to diaryliodonium triflates have been developed in the sustainable solvent ethyl acetate. The first method yields the recently reported aryl(dimethylisoxazolyl)iodonium triflates, circumventing the need for stepwise synthesis of this chemoselective arylating reagent. The second method gives other types of diaryliodonium salts, and the scalability of the protocols was exhibited with two >45 mmol scale-ups with impressively low -factors.

Nonadiabatic Charge Transfer within Photoexcited Nickel Porphyrins.

Metalloporphyrins with open d-shell ions can drive biochemical energy cycles. However, their utilization in photoconversion is hampered by rapid deactivation. Mapping the relaxation pathways is essential for elaborating strategies that can favorably alter the charge dynamics through chemical design and photoexcitation conditions.
